[Solved]creating tabs

DenisKormalev

Use this instead of last line in your ctor
@
centralWidget->setLayout(mainLayout);
@

alfah

denis,

i can jus use centralWidget?? wat is it??

i get the follwing error " invalid use of member".

alfah

Eddy

I think you need to use
@setCentralWidget @ first

alfah

:( it does work tht way either.

DenisKormalev

oops, I meant
@
centralWidget()->setLayout(mainLayout);
@

Eddy, looks like it is form created from designer, so central widget should be there.

Tabs is the class derived from QMainWindow ? Can you show us the header and part of the code where you instantiate the Tabs class ?

alfah

:D :D yeaa denis i got it right, Thank you!

so if i want to create buttons in the history tab? how to i go abt it???. I meant how do i acces each tab separately??

alfah

Eddy

Did you use it like this ? :

this is the way moc does it when looking in the ui_tabs.h file
@centralwidget = new QWidget(Tabs); // it is just a temporary name
...
Tabs->setCentralWidget(centralwidget);@

@Denis
Yes, you are right!

EDIT : too late ;)

alfah

eddy,

@
Tabs::Tabs(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::Tabs)
{
ui->setupUi(this);
tabWidget = new QTabWidget;
tabWidget->addTab(new QWidget,tr("History"));
tabWidget->addTab(new QWidget,tr("Calender"));
tabWidget->addTab(new QWidget,tr("Statistics"));
mainLayout = new QVBoxLayout;
mainLayout->addWidget(tabWidget);
centralWidget()->setLayout(mainLayout);

}
@

i still do not know how to make individual buttons on each tab :(

alfa

Eddy

have a look at
@indexOf()@

cincirin

@QTabWidget::widget(int index)@ return the tab page.
Then you can create buttons with returned parent.

alfah

u mean tabWidget->indexOf()???

But i have not named each tab:(

You can event add custom widgets to the tab widget, so go this way:

@
Tabs::Tabs(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::Tabs)
{
ui->setupUi(this);
tabWidget = new QTabWidget;

QWidget* pHistory = new QWidget;
// fill pHistory here
QPushButton* p = new QPushButton(tr("my text"), pHistory);


tabWidget->addTab(pHistory,tr("History"));
tabWidget->addTab(new QWidget,tr("Calender"));
tabWidget->addTab(new QWidget,tr("Statistics"));
mainLayout = new QVBoxLayout;
mainLayout->addWidget(tabWidget);
centralWidget()->setLayout(mainLayout);

}
@

Eddy

in that case use cinrin's solution :

for example :

@ QPushButton* ppp = new QPushButton("testing" );
QHBoxLayout* hhh = new QHBoxLayout();
hhh->addWidget(ppp);
ui->tabWidget->widget(1)->setLayout(hhh);@

I set up an example layout for you to control size and position.

EDIT : this time Gerolf was faster ;)

alfah

gerolf,

yea i could make buttons. Now im working on somethin a bit more complex than a single button.
I have made a calender using an array of buttons, its the same thing like the default calender.

Would it be possible to put in the whole calender in to one of the tab, jus as you have created a single button.???
It requires mainly 4 funtions to create the whole calender
@
initMemberVariable();

initMonthYear();

initWeekDay();

createLayout();

@

@
bool CalenderForm::initMemberVariable()
{

selectedDate=QDate::currentDate();

controlsLayout = new QGridLayout();

monthValue=selectedDate.month();

pLabelStatus=new QLabel;

pLabelStatus->setStyleSheet("color:black");


for(int i=0;i<6;i++)
{
    for(int j=0;j<7;j++)
    {

       cellBut[i][j]=new QPushButton(this);
       connect(cellBut[i][j],SIGNAL(clicked()),this,SLOT(onClickAction()));
       cellBut[i][j]->setFlat(true);

    }
}
return true;

}
@

This is where the buttons are created. I want them to be created in the calender tab.

Could you guide me on how to go abt it?

bq. This is where the buttons are created. I want them to be created in the calender tab.

try this

@ QGridLayout* grid = new QGridLayout();

for(int i=0;i<6;i++)     {
    for(int j=0;j<7;j++)         {
        cellBut[i][j]=new QPushButton(QString("%1 , %2").arg(i).arg(j));
        connect(cellBut[i][j],SIGNAL(clicked()),this,SLOT(onClickAction()));
        cellBut[i][j]->setFlat(true);
        grid ->addWidget(cellBut[i][j],i,j);
    }
}

ui->tabWidget->widget(1)->setLayout(grid );@
